Firewall Grommet part number needed (1978)
On the passenger side of the firewall, very close to the fender, there's a hole in the firewall that two windshield washer fluid hoses run through. There's a grommet in this hole that protects those hoses from the sharp, metal edge. Does anyone know what the part number is for this grommet? I can't seem to track it down in the PET diagrams.
Thanks.
Thanks.

Grommets are poorly documented in the parts catalog- the only one that is listed for the hoses that pass through the passenger side fender area are 021 119 569A, which is for the vacuum hoses to the carbon canister. Is this the grommet you're looking for, or the larger one that all the wiring to the washer pumps runs through?

Not a pic of my car but it shows the area I’m referencing.

I’ve got a Harbor Freight nearby so I’ll check out that kit for $5. Seems like a pretty good deal if one of them will fit.

On the '89 and '93 I have here, the OD of the grommet flange is 51 mm and the central portion is 28-30mm or so. Stoddard and AutoAtlanta have the best selection of Porsche grommets with actual pictures but without measurements it's hard to know which (if any) is correct. Best bet might be a 1-1/4" or 1-1/2" generic grommet cut down to fit.

928 628 757 00 is listed as a non-pictured 'extra' on the 78-82 washer hose assembly page in PET, the picture at AutoAtlanta is promising. Might be worth a $7 gamble to see if it is correct.

Rob you nailed it. I ordered this grommet and it was a perfect fit. The center section was sealed up so I had to open it up with some scissors but otherwise it seems to be spot on.
